CAY10761 is an inhibitor of ectonucleotide pyrophosphatase/phosphodiesterase 1. It also inhibits mushroom tyrosinase and urease from jack bean, P. mirabilis, and B. pasteurii.

5,5′-(1,3-Propanediyl)bis-1,3,4-oxadiazole-2(3H)-thione is a weak inhibitor for snake venom and human recombinant phosphodiesterase 1 with IC50 of 429 and 467 μM. 5,5′-(1,3-Propanediyl)bis-1,3,4-oxadiazole-2(3H)-thione inhibits mushroom tyrosinase weakly, with Ki of 1.9 μM[1][2].
